Send email automatically (php) and add text from JavaScript [duplicate]

Question

I have made/got a code that will get a location with java script. The idea is that it automatically emails someone with the location from the Javascript. However, how would you get the the location in the email, and how would you make it send automatically?

My code is :

<!DOCTYPE html>
<html>
<head>
<title>TestPage</title>
</head>
<body>
<h1>Test</h1>
<p>Your Loaction:
<p id="demo"></p>
<script>
var x = document.getElementById("demo");

function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition, showError);
    } else { 
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}

function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude;
}

function showError(error) {
    switch(error.code) {
        case error.PERMISSION_DENIED:
            x.innerHTML = "User denied the request for Geolocation."
            break;
        case error.POSITION_UNAVAILABLE:
            x.innerHTML = "Location information is unavailable."
            break;
        case error.TIMEOUT:
            x.innerHTML = "The request to get user location timed out."
            break;
        case error.UNKNOWN_ERROR:
            x.innerHTML = "An unknown error occurred."
            break;
    }
}
window.onload = getLocation();
</script>
<?php
$to      = '[email protected]';
$subject = 'Subject';
$message = 'Your location is' <p id="demo">''</p>;

mail($to, $subject, $message,);
?>
</body>
</html>

So i want the php to automatically send and put the Location in the email -- is this even possible? does anyone know how?

You are mixing PHP and JavaScript.

PHP is executed on the server, THEN the result is sent to the client and renderd, THEN JavaScript is run. Your code is not syntactically correct (because of the <p> tag around the PHP string), but even if it were, it would simply send an e-mail everytime someone requests the webpage, no matter whether they look at it, or whether they have JavaScript or geolocation enabled.

What you want, for whatever reason, is two separate pages - the HTML + JavaScript one which will attempt to get the user's location, and a PHP script. The JavaScript code will need to send an AJAX request to the PHP script with the location, once it obtained it.
